Finding a great topic can be hard for a lot of National History Day participants. This is especially when your team has numerous interests that stretch a variety of fields. Regardless, there are three key tenets you should stick to when choosing a great topic.
Remember – National History Day is a 9-month long research project. With that being said, you have to make sure that you love your topic and can’t see yourself getting bored with within the first couple of weeks.
Of course, you should try to pick a topic that is related to your interests, as more passion almost always yields more genuine writing.
Consider this simple exercise - imaging having to describe two different people to your parents: one who has been your best friend since preschool, and the other a stranger you saw walking down the street. Who do you think you could describe better?
I’ll admit to nearly making this mistake in the past – in fact, I can attest that I’ve almost committed this error more than once. However, unless you’re a history buff like some of my teammates used to be, chances are, your topics won’t be too obscure.
“Well-documented” can have a lot of connotations, but in the context of National History Day, make sure that your topic has plenty of print and video resources, some professors and (maybe even) historical figures that can be interviewed, and information that corroborates among multiple sources.
Note: During the national awards ceremony in 2019, one of my teachers told me something observed as we were leaving the stadium:
Am I the only one that noticed that a majority of the winners chose topics related to U.S. history?
Looking at the recent winners list will reveal the same trend, and truth be told, I should’ve been able to deduce from our own personal experiences: our projects that dealt with American history seemed to fare better than world history projects. This doesn’t mean that I discourage you from picking an international topic, but my hunch is that the judges seem to relate better to topics they may have more prior information on and are more familiar with. But of course, do as you please.
As much as you can say that finding a topic you like is the most important tenet to stick by, I actually think that finding a topic that fits with the theme is what makes a topic truly great. After all, from year to year, the only thing that really changes with National History Day is the historical theme.
Furthermore, there is absolutely no way to fix a topic with a poor connection to the theme. No matter how masterful you may be with rhetoric, if you can’t communicate why the topic “breaks a barrier” or “takes a stand”, you might as well consider all of your efforts wasted.
One of the ways to check if a topic fits well with a theme is to try the old elevator pitch technique: set aside your friend or teacher, and tell him/her about your topic and its connection to the theme in 30 seconds. If they can’t repeat the main points of your argument back to you, then either (a.) your delivery is convoluted or (b.) your topic doesn’t connect to the theme.
Pretty much anything is fair game for National History Day, as long as the topic/event occurred at least 20 years ago (this number should be fact-checked, but this is the rule of thumb I like to keep when brainstorming topics). If you’re having trouble, try checking out these resources:
History behind News (make sure to matriculate non-partisan news sources)
Family History
Personal Passions
Pop Culture (my teammate stumbled upon Alan Turing while watching a trailer on the The Imitation Game.

Unmodified entities have entity codes and names which conform to the Federal Information Processing Standard 5-2. Area values in square miles are derived from land polygon area values from the U.S. Census Bureau's TIGER database.
The state-level boundary data are highly generalized and suitable for use in small scale (1:20,000,000) thematic mapping applications. No accuracy tests were performed.
The generalized data do NOT include 1) boundaries for the Aleutian Islands in the Eastern Hemisphere, 2) boundaries for Hawaiian Islands west of -160.555771 degrees longitude, 3) very small polygons because of coordinate thinning, and 4) water polygons. This data set provides the land area in square miles and number of acres for each state equivalent. The land area values are based on the area of land polygons from the U.S. Census Bureau's TIGER database. If a state is composed of several polygons, the area value assigned to each polygon is the land area value of the entire state (for the purpose of choropleth mapping). The state-level boundary for Maryland was modified to include the District of Columbia (D.C.), because Agricultural Census data for D.C. are not reported separately. State-level Federal Information Processing (FIPS) codes are used to identify states. Because Maryland and D.C. state boundaries were aggregated, Maryland's FIPS code 24 represents Maryland (24) and D.C. (11).
No topological checks were performed on the data.

title=Spring Data Mongo transaction synchronization does not find a bound DB date=2012-11-25 type=post tags=blog status=published ~~~~~~
There's an issue with Spring Data Mongo when used in the context of an application with existing PlatformTransactionManager
-based transaction management setup, where Spring's TransactionSynchronizationManager
tries to find the bound Spring Data Mongo DB
instance, but fails and throws an exception.
The issue is resolved, but you wouldn't know that if you checked the Spring Data MongoDB web site because there is no mention of the later releases. This issue is fixed in the latest releases, however, versions, 1.1.1.RELEASE
.
If you're using Maven, you can specify the latest revision with the following Maven coordinates:
<dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-mongodb</artifactId> <version>1.1.1.RELEASE</version> </dependency>
The error looks like this:
java.lang.IllegalStateException: No value for key [Mongo: localhost:27017] bound to thread [1128017935@qtp-1027055145-3] at org.springframework.transaction.support.TransactionSynchronizationManager.unbindResource(TransactionSynchronizationManager.java:209) ~[spring-tx-3.1.1.RELEASE.jar:3.1.1.RELEASE] at org.springframework.transaction.support.ResourceHolderSynchronization.beforeCompletion(ResourceHolderSynchronization.java:69) ~[spring-tx-3.1.1.RELEASE.jar:3.1.1.RELEASE] at org.springframework.transaction.support.TransactionSynchronizationUtils.triggerBeforeCompletion(TransactionSynchronizationUtils.java:106) ~[spring-tx-3.1.1.RELEASE.jar:3.1.1.RELEASE] at org.springframework.transaction.support.AbstractPlatformTransactionManager.triggerBeforeCompletion(AbstractPlatformTransactionManager.java:937) [spring-tx-3.1.1.RELEASE.jar:3.1.1.RELEASE] at org.springframework.transaction.support.AbstractPlatformTransactionManager.processCommit(AbstractPlatformTransactionManager.java:738) [spring-tx-3.1.1.RELEASE.jar:3.1.1.RELEASE] at org.springframework.transaction.support.AbstractPlatformTransactionManager.commit(AbstractPlatformTransactionManager.java:723) [spring-tx-3.1.1.RELEASE.jar:3.1.1.RELEASE] at org.springframework.transaction.interceptor.TransactionAspectSupport.commitTransactionAfterReturning(TransactionAspectSupport.java:393) [spring-tx-3.1.1.RELEASE.jar:3.1.1.RELEASE]

The Urine Flow Rate (or urine excretion rate) is a measurement of the quantity of urine produced in a specified period of time. Urine analyte concentrations from single determinations (spot urines) can vary depending on level of hydration. Due to this variation, the urine flow rate, when used in conjunction with analyte concentration measured on spot urine, can produce a better measure of analyte excretion rate, especially in the context of exposure to environmental chemicals. The urine excretion rate (mg/min) is the product of the urine flow rate (mL/min) and the urine analyte concentration (mg/mL).
All examined participants aged 3 years and older were eligible.
Participants will be asked to record the time of their last void before coming to the mobile examination centers (MEC). Participants will then be asked to void at the MEC where the time of collection and volume of the urine will be recorded. The volume of the urine sample collected at the MEC will be measured and the urine flow rate will be calculated from this information. Up to three voids were collected for the purpose of ensuring sufficient total volume for various analyses, with volumes and timing recorded. Collected samples were composited then aliquoted into separate vessels such that all analyses can be conducted on the composite sample. The figure below depict the scheme for collecting urine samples and recording time duration covered for each urine void.
The urine flow rate is calculated by dividing the volume of the urine sample collected by the time duration between the previous urine void and the urine sample collection in the MEC. There may be a maximum of 3 urine flow rates associated with each urine void for a participant, but that depends on the total number of spot urines collected in the MEC.
Since all urinary analyte concentrations are measured in the composite sample, the urinary flow rate associated with a given urinary analyte concentration is calculated using the total volume of urine collected and total time duration covered by all urine voids. How to perform this calculation is described below under “Analytic Note.”
There were no changes to the lab method or lab equipment for this component in the NHANES 2015-2016 cycle.
Random/spot urine samples are processed and weighed in the MEC.
Detailed instructions on specimen collection and processing are discussed in the NHANES Laboratory Procedures Manual (LPM).
The NHANES quality assurance and quality control (QA/QC) protocols meet the 1988 Clinical Laboratory Improvement Act mandates. Detailed QA/QC instructions are discussed in the NHANES LPM.
Mobile Examination Centers (MECs)
Laboratory team performance is monitored using several techniques. NCHS and contract consultants use a structured competency assessment evaluation during visits to evaluate both the quality of the laboratory work and the quality-control procedures. Each laboratory staff member is observed for equipment operation, specimen collection and preparation; testing procedures and constructive feedback are given to each staff member. Formal retraining sessions are conducted annually to ensure that required skill levels were maintained.
The data were reviewed. Incomplete data or improbable values were identified and corrected.
Refer to the 2015-2016 Laboratory Data Overview for general information on NHANES laboratory data.
Conceptually, urinary flow rate for the composite urine sample is calculated as: Urinary flow rate = (total urine volume)/(total time duration)
The exact form of formula is different depending on how many urine spot urine samples are collected at the MEC. In general, the calculation should involve only the information on the first urine collection through the last urine collection with non-zero, non-missing volume and non-missing time duration. Three forms of formulae are described with specification of when to use.
1) Formula involving the volume and time information from the first urine collection.
Many survey participants provided sufficient volume of urine at the first collection, and there was no 2nd or 3rd urine collection. For those, urinary flowrate associated with urinary analyte concentrations is calculated as:
Urinary flowrate = URXVOL1/ URXTIME1 = URDFLOW1
This formula also is used for survey participants who: has the volume of second urine collection recorded as zero and the volume of third urine collection recorded as missing; or has the volumes of second and third urine collection recorded as zero.
2) Formula involving the volume and time information from first and second urine collections.
For survey participants who provided two spot urine samples, urinary flowrate associated with urinary analyte concentrations is calculated as:
Urinary flowrate = (URXVOL1 + URXVOL2) / (URXTIME1 + URXTIME2)
This formula also is used for survey participants who has the volume of first urine collection recorded as zero and the volume of second urine collection recorded as > zero with missing volume of the third urine collection (i.e., no or very little urine was collected for the first attempt to collect a urine sample and there was no third urine sample).
3) Formula involving the volume and time information from the first, second, and third urine collections.
For survey participants who provided three spot urine samples, urinary flowrate associated with urinary analyte concentrations is calculated as:
Urinary flow rate= (URXVOL1 + URXVOL2 + URXVOL3)/(URXTIME1 + URXTIME2 + URXTIME3)
Please note that this formula also should be used when URXVOL1 and/or URXVOL2 is zero and URXVOL3 > 0 (i.e., no or very little urine was collected for the first and/or second urine attempt to collect urine samples).
Please note that the time of last urine void before arriving the MEC was based on self-reported information from the participant, therefore, the data may be subject to reporting error. Analysts should examine the data distribution and use their subject-matter knowledge to decide whether to include, trim, or exclude any potential outliers in their analyses.
Demographic and Other Related Variables
The analysis of NHANES laboratory data must be conducted using the appropriate survey design and demographic variables. The NHANES 2015-2016 Demographics File contains demographic data, health indicators, and other related information collected during household interviews as well as the sample weight variables. The recommended procedure for variance estimation requires use of stratum and PSU variables (SDMVSTRA and SDMVPSU, respectively) in the demographic data file.
This laboratory data file can be linked to the other NHANES data files using the unique survey participant identifier (i.e., SEQN).
Detection Limits
Since this data is
calculated the use of lower limits of detection (LLODs) isn’t applicable.
Please refer to the NHANES Analytic Guidelines and the on-line NHANES Tutorial for further details on the use of sample weights and other analytic issues.

Abstract: Some of the most compelling applications of online convex optimization, including online prediction and classiﬁcation, are unconstrained: the natural feasible set is Rn . Existing algorithms fail to achieve sub-linear regret in this setting unless constraints on the comparator point ˚ are known in advance. We present algox rithms that, without such prior knowledge, offer near-optimal regret bounds with respect to any choice of ˚. In particular, regret with respect to ˚ = 0 is constant. x x We then prove lower bounds showing that our guarantees are near-optimal in this setting. 1

HeapTrack manager provides functions to allocate and free storage from a
configured heap which inherits from IHeap. The calling context is going to
match the heap being used.
HeapTrack is useful for detecting memory leaks, double frees and buffer
overflows. There is a performance overhead cost when using heap track as
well as a size impact. Every alloc will include a
Tracker
structure (plus memory to get proper alignment of the stucture) at
the end of the buffer that should not be modified by the user. It is
important to remember this when deciding on heap sizes and you may have to
adjust the total size or buffer sizes (for HeapBuf/HeapMultiBuf).
ROV displays peaks and current in-use for both allocated memory (requested
size + Tracker structure) and requested memory (without Tracker).
The information stored in the tracker packet is used to display information
in RTOS Object Viewer (ROV) as well as with the printTask and printHeap
functions.
The asserts used in this module are listed below and include error checking
for double frees, calling printHeap with a null handle, buffer overflows
and deleting a non empty heap.
| struct HeapTrack_Tracker |
|
Structure added to the end of each allocated block
typedef struct HeapTrack_Tracker {
UArg scribble;
SizeT size;
UInt32 tick;
} HeapTrack_Tracker;
DETAILS
When a block is allocated from a HeapTrack heap with a size,
internally HeapTrack calls Memory_alloc on the configured
heap. The value of sizeof(HeapTrack_Tracker)
is added to the requested size.
For example, if the caller makes the following call (where heapHandle
is an HeapTrack handle that has been converted to an IHeap_Handle).
buf = Memory_alloc(heapHandle, MYSIZE, MYALIGN, &eb);
Internally, HeapTrack will make the following call
(where size is MYSIZE, align is MYALIGN and obj is the HeapTrack handle).
block = Memory_alloc(obj->heap, size + sizeof(HeapTrack_Tracker), align, &eb);
When using HeapTrack, depending on the actual heap
(i.e.
heap), you might need to make adjustments to the heap
(e.g. increase the blockSize if using a HeapBuf instance).
The HeapTrack module manages the contents of this structure and should
not be directly accessing them.

Gentle spicing gives warmth and depth to this special dish. Make sure your fish is spanking fresh to let its flavour shine through.
Preheat the oven to 180C/350F/Gas 4.
Scrub the mussels, remove the beards and discard any mussels that remain open when tapped against the side of the sink.
Heat the olive oil in a large, heavy-based pan that has a lid. Add the onion and the parsley and cook gently until the onion is soft but not brown.
Add the mussels, salt and freshly ground black pepper and the white wine. Bring the wine to the boil, put the lid on and shake the mussels about. Leave the pan on the heat and cook for 3-5 minutes or until the mussels are open. Discard any that remain closed.
Strain the mussels and set aside, reserving the cooking liquor. Pour the liquor through a fine sieve into a clean jug to remove any grit.
For the sauce, melt the butter in a saucepan over a low heat. Gently cook the onion, carrot and celery until soft. Stir in the curry powder and continue cooking for a few minutes.
Add 150ml/5fl oz of the cooking liquor from the mussels, stir well and cook for another minute. Stir in the double cream, bring back to the boil then add the diced potatoes and cook for about five minutes or until the potatoes have softened.
Remove the mussels from their shells, add them to the cream mixture and warm them through. Finish the sauce with the chopped chives and season with salt and freshly ground black pepper and squeeze of lemon juice.
For the salmon, wash the fish and dry the skin thoroughly. With a sharp knife, cut diagonal slashes in the skin and season with salt and freshly ground black pepper.
Heat a non-stick ovenproof frying pan over a medium heat then add the vegetable oil. Cook the salmon, skin-side down, for 4-5 minutes or until the skin is crisp, then turn the fish over and transfer the pan to the oven for 3-4 minutes or until the fish is just cooked through.
To serve, place the curried mussels in a large bowl and arrange the salmon fillets on top.

The HTML5 canvas element can be used to write image filters. What you need to do is draw an image onto a canvas, read back the canvas pixels, and run your filter on them. You can then write the result onto a new canvas (or heck, just reuse the old one.)
Sounds simple? Good. Let's get cracking!
First, retrieve the image pixels:
Filters = {}; Filters.getPixels = function(img) { var c = this.getCanvas(img.width, img.height); var ctx = c.getContext('2d'); ctx.drawImage(img); return ctx.getImageData(0,0,c.width,c.height); }; Filters.getCanvas = function(w,h) { var c = document.createElement('canvas'); c.width = w; c.height = h; return c; };
Next, we need a way to filter images. How about a filterImage
method that takes a filter and an image and returns the filtered pixels?
Filters.filterImage = function(filter, image, var_args) { var args = [this.getPixels(image)]; for (var i=2; i<arguments.length; i++) { args.push(arguments[i]); } return filter.apply(null, args); };
Now that we have the pixel processing pipeline put together, it's time to write some simple filters. To start off, let's convert the image to grayscale.
Filters.grayscale = function(pixels, args) { var d = pixels.data; for (var i=0; i<d.length; i+=4) { var r = d[i]; var g = d[i+1]; var b = d[i+2]; // CIE luminance for the RGB // The human eye is bad at seeing red and blue, so we de-emphasize them. var v = 0.2126*r + 0.7152*g + 0.0722*b; d[i] = d[i+1] = d[i+2] = v } return pixels; };
Adjusting brightness can be done by adding a fixed value to the pixels:
Filters.brightness = function(pixels, adjustment) { var d = pixels.data; for (var i=0; i<d.length; i+=4) { d[i] += adjustment; d[i+1] += adjustment; d[i+2] += adjustment; } return pixels; };
Thresholding an image is also quite simple. You just compare the grayscale value of a pixel to the threshold value and set the color based on that:
Filters.threshold = function(pixels, threshold) { var d = pixels.data; for (var i=0; i<d.length; i+=4) { var r = d[i]; var g = d[i+1]; var b = d[i+2]; var v = (0.2126*r + 0.7152*g + 0.0722*b >= threshold) ? 255 : 0; d[i] = d[i+1] = d[i+2] = v } return pixels; };
Convolution filters are very useful generic filters for image processing. The basic idea is that you take the weighed sum of a rectangle of pixels from the source image and use that as the output value. Convolution filters can be used for blurring, sharpening, embossing, edge detection and a whole bunch of other things.
Filters.tmpCanvas = document.createElement('canvas'); Filters.tmpCtx = Filters.tmpCanvas.getContext('2d'); Filters.createImageData = function(w,h) { return this.tmpCtx.createImageData(w,h); }; Filters.convolute = function(pixels, weights, opaque) { var side = Math.round(Math.sqrt(weights.length)); var halfSide = Math.floor(side/2); var src = pixels.data; var sw = pixels.width; var sh = pixels.height; // pad output by the convolution matrix var w = sw; var h = sh; var output = Filters.createImageData(w, h); var dst = output.data; // go through the destination image pixels var alphaFac = opaque ? 1 : 0; for (var y=0; y<h; y++) { for (var x=0; x<w; x++) { var sy = y; var sx = x; var dstOff = (y*w+x)*4; // calculate the weighed sum of the source image pixels that // fall under the convolution matrix var r=0, g=0, b=0, a=0; for (var cy=0; cy<side; cy++) { for (var cx=0; cx<side; cx++) { var scy = sy + cy - halfSide; var scx = sx + cx - halfSide; if (scy >= 0 && scy < sh && scx >= 0 && scx < sw) { var srcOff = (scy*sw+scx)*4; var wt = weights[cy*side+cx]; r += src[srcOff] * wt; g += src[srcOff+1] * wt; b += src[srcOff+2] * wt; a += src[srcOff+3] * wt; } } } dst[dstOff] = r; dst[dstOff+1] = g; dst[dstOff+2] = b; dst[dstOff+3] = a + alphaFac*(255-a); } } return output; };
Here's a 3x3 sharpen filter. See how it focuses the weight on the center pixel. To maintain the brightness of the image, the sum of the matrix values should be one.
Filters.filterImage(Filters.convolute, image, [ 0, -1, 0, -1, 5, -1, 0, -1, 0 ] );
Here's an another example of a convolution filter, the box blur. The box blur outputs the average of the pixel values inside the convolution matrix. The way to do that is to create a convolution matrix of size NxN where each of the weights is 1 / (NxN). That way each of the pixels inside the matrix contributes an equal amount to the output image and the sum of the weights is one.
Filters.filterImage(Filters.convolute, image, [ 1/9, 1/9, 1/9, 1/9, 1/9, 1/9, 1/9, 1/9, 1/9 ] );
We can make more complex image filters by combining existing filters. For example, let's write a Sobel filter. A Sobel filter computes the vertical and horizontal gradients of the image and combines the computed images to find edges in the image. The way we implement the Sobel filter here is by first grayscaling the image, then taking the horizontal and vertical gradients and finally combining the gradient images to make up the final image.
Regarding terminology, "gradient" here means the change in pixel value at an image position. If a pixel has a left neighbour with value 20 and a right neighbour with value 50, the horizontal gradient at the pixel would be 30. The vertical gradient has the same idea but uses the above and below neighbours.
var grayscale = Filters.filterImage(Filter.grayscale, image); // Note that ImageData values are clamped between 0 and 255, so we need // to use a Float32Array for the gradient values because they // range between -255 and 255. var vertical = Filters.convoluteFloat32(grayscale, [ -1, 0, 1, -2, 0, 2, -1, 0, 1 ]); var horizontal = Filters.convoluteFloat32(grayscale, [ -1, -2, -1, 0, 0, 0, 1, 2, 1 ]); var final_image = Filters.createImageData(vertical.width, vertical.height); for (var i=0; i<final_image.data.length; i+=4) { // make the vertical gradient red var v = Math.abs(vertical.data[i]); final_image.data[i] = v; // make the horizontal gradient green var h = Math.abs(horizontal.data[i]); final_image.data[i+1] = h; // and mix in some blue for aesthetics final_image.data[i+2] = (v+h)/4; final_image.data[i+3] = 255; // opaque alpha }
To cap off our journey into convolution, here's a little toy for you to play with: A custom 3x3 convolution filter! Yay!
 For instance, try implementing a Laplace filter in the convolution toy above and see what it does.
I hope this small article was useful in introducing the basic concepts of writing image filters in JavaScript using the HTML canvas tag. I encourage you to go and implement some more image filters, it's quite fun!
If you need better performance from your filters, you can usually port them to use WebGL fragment shaders to do the image processing. With shaders, you can run most simple filters in realtime, which allows you to use them for post-processing video and animations.


Many applications will create their menus and dialog boxes from scratch, using various GenInteraction and GenTrigger objects. Several system components, however, use a standard base format across all applications. For these components, GEOS provides a number of controller objects.
A controller object is one that provides UI gadgetry to control a certain set of features. For example, the GenViewControl object provides all the UI--including menus, dialogs, and tool bars, if appropriate--to alter a GenView's scaling and other features. Many libraries such as the text library provide controller objects that make the use of the library almost trivial.
To make inclusion of these controllers even easier, the UI offers a GenToolControl; this object provides all the functionality and UI gadgetry to allow the user to configure his own toolbars and menus from the tools provided by a controller.
Finally, developers writing libraries or suites of applications may wish to create their own controller classes. This is neither difficult nor complex, though it will be done primarily by programmers writing libraries for use by many applications.
This chapter describes what controllers are and how they work. It also discusses which controllers are available in the system, as well as the GenToolControl object and how it's used. Finally, it details how to create your own controller classes. In order to fully understand this chapter, you should be familiar first with the generic UI, menus and dialog boxes, and the General Change Notification mechanism.

Notes: 1980 was the inaugural year. The course was short for many years; some years, it was more than a kilometer
short. For 1988, the course was determined to have been 550 meters short. The 1995 course was also reported as
550 meters short but the times indicate it was shorter yet. The 2014
results did not provide gun times for women; the 2015 results provided only net
times. In 2011, Najim El Qady (MAR) finished 1st in 59:41 but was
disqualified for drug use. El Qady was also disqualified in 2016 after
finishing first in 1:00:18.

Content scripts are files that run in the context of web pages. By using the standard Document Object Model (DOM), they are able to read details of the web pages the browser visits, make changes to them and pass information to their parent extension.
Content scripts can access Chrome APIs used by their parent extension
by exchanging messages with the extension.
They can also access the URL of an extension's file with
chrome.runtime.getURL()
and use the result the same as other URLs.
//Code for displaying <extensionDir>/images/myimage.png: var imgURL = chrome.runtime.getURL("images/myimage.png"); document.getElementById("someImage").src = imgURL;
Additionally, content script can access the following chrome APIs directly:
Content scripts are unable to access other APIs directly.
Content scripts live in an isolated world, allowing a content script to makes changes to its JavaScript environment without conflicting with the page or additional content scripts.
An extension may run in a web page with code similar to the example below.
<html> <button id="mybutton">click me</button> <script> var greeting = "hello, "; var button = document.getElementById("mybutton"); button.person_name = "Bob"; button.addEventListener("click", function() { alert(greeting + button.person_name + "."); }, false); </script> </html>
That extension could inject the following content script.
var greeting = "hola, "; var button = document.getElementById("mybutton"); button.person_name = "Roberto"; button.addEventListener("click", function() { alert(greeting + button.person_name + "."); }, false);
Both alerts would appear if the button was pressed.
Isolated worlds do not allow for content scripts, the extension, and the web page to access any variables or functions created by the others. This also gives content scripts the ability to enable functionality that should not be accessible to the web page.
Content Scripts can be programmatically or declaratively injected.
Use programmatic injection for content scripts that need to run on specific occasions.
To inject a programmatic content script, provide the activeTab permission in the manifest. This grants secure access to the active site's host and temporary access to the tabs permission, enabling the content script to run on the current active tab without specifying cross-origin permissions.
{ "name": "My extension", ... "permissions": [ "activeTab" ], ... }
Content scripts can be injected as code.
chrome.runtime.onMessage.addListener( function(message, callback) { if (message == “changeColor”){ chrome.tabs.executeScript({ code: 'document.body.style.backgroundColor="orange"' }); } });
Or an entire file can be injected.
chrome.runtime.onMessage.addListener( function(message, callback) { if (message == “runContentScript”){ chrome.tabs.executeScript({ file: 'contentScript.js' }); } });
Use declarative injection for content scripts that should be automatically run on specified pages.
Declaratively injected scripts are registered in the manifest
under the "content_scripts"
field.
They can include JavaScript files, CSS files or both.
All auto-run content scripts must specify
match patterns.
{ "name": "My extension", ... "content_scripts": [ { "matches": ["http://*.nytimes.com/*"], "css": ["myStyles.css"], "js": ["contentScript.js"] } ], ... }
| Name | Type | Description |
|---|---|---|
matches
|
array of strings | Required. Specifies which pages this content script will be injected into. See Match Patterns for more details on the syntax of these strings and Match patterns and globs for information on how to exclude URLs. |
css |
array of strings | Optional. The list of CSS files to be injected into matching pages. These are injected in the order they appear in this array, before any DOM is constructed or displayed for the page. |
js |
|
Optional. The list of JavaScript files to be injected into matching pages. These are injected in the order they appear in this array. |
match_about_blank
|
boolean |
Optional.
Whether the script should inject into an about:blank frame
where the parent or opener frame matches one of the patterns declared in
matches . Defaults to false.
|
Specified page matching is customizable by including the following fields in the manifest registration.
| Name | Type | Description |
|---|---|---|
exclude_matches
|
array of strings | Optional. Excludes pages that this content script would otherwise be injected into. See Match Patterns for more details on the syntax of these strings. |
include_globs
|
array of strings |
Optional.
Applied after matches
to include only those URLs that also match this glob.
Intended to emulate the
@include
Greasemonkey keyword.
|
exclude_globs
|
array of string |
Optional.
Applied after matches to exclude URLs that match this glob.
Intended to emulate the
@exclude
Greasemonkey keyword.
|
The content script will be injected into a page if its URL matches any
matches
pattern and any include_globs
pattern,
as long as the URL doesn't also match an exclude_matches
or
exclude_globs
pattern.
Because the matches
property is required,
exclude_matches
, include_globs
,
and exclude_globs
can only be used to limit which pages will be affected.
The following extension would injected the content script into http://www.nytimes.com/ health but not into http://www.nytimes.com/ business .
{ "name": "My extension", ... "content_scripts": [ { "matches": ["http://*.nytimes.com/*"], "exclude_matches": ["*://*/*business*"], "js": ["contentScript.js"] } ], ... }
Glob properties follow a different, more flexible syntax than match patterns. Acceptable glob strings are URLs that may contain "wildcard" asterisks and question marks. The asterisk * matches any string of any length, including the empty string, while the question mark ? matches any single character.
For example, the glob http:// ??? .example.com/foo/ * matches any of the following:
However, it does not match the following:
This extension would inject the content script into http:/www.nytimes.com/ arts /index.html and http://www.nytimes.com/ jobs /index.html but not into http://www.nytimes.com/ sports /index.html.
{ "name": "My extension", ... "content_scripts": [ { "matches": ["http://*.nytimes.com/*"], "include_globs": ["*nytimes.com/???s/*"], "js": ["contentScript.js"] } ], ... }
This extension would inject the content script into http:// history .nytimes.com and http://.nytimes.com/ history but not into http:// science .nytimes.com or http://www.nytimes.com/ science .
{ "name": "My extension", ... "content_scripts": [ { "matches": ["http://*.nytimes.com/*"], "exclude_globs": ["*science*"], "js": ["contentScript.js"] } ], ... }
One, all, or some of these can be included to achieve the correct scope.
{ "name": "My extension", ... "content_scripts": [ { "matches": ["http://*.nytimes.com/*"], "exclude_matches": ["*://*/*business*"], "include_globs": ["*nytimes.com/???s/*"], "exclude_globs": ["*science*"], "js": ["contentScript.js"] } ], ... }
When JavaScript files are injected into the web page
is controlled by the run_at
field.
The preffered and default field is
"document_idle"
,
but can also be specified as
"document_start"
or
"document_end"
if needed.
{ "name": "My extension", ... "content_scripts": [ { "matches": ["http://*.nytimes.com/*"], "run_at": "document_idle", "js": ["contentScript.js"] } ], ... }
| Name | Type | Description |
|---|---|---|
document_idle
|
string |
Prefered.
Use "document_idle" whenever possible.
The browser chooses a time to inject scripts between "document_end" and immediately after the
window.onload
event fires.
The exact moment of injection depends on how complex the document is
and how long it is taking to load, and is optimized for page load speed.
Content scripts running at "document_idle"
do not need to listen for the window.onload
event,
they are guaranteed to run after the DOM is complete.
If a script definitely needs to run after window.onload ,
the extension can check if onload has already fired
by using the
document.readyState
property.
|
document_start
|
string |
Scripts are injected after any files from css ,
but before any other DOM is constructed or any other script is run.
|
document_end
|
string | Scripts are injected immediately after the DOM is complete, but before subresources like images and frames have loaded. |
The "all_frames"
field allows the extension to specify if
JavaScript and CSS files should be injected into all frames matching
the specified URL requirements or only into the topmost frame in a tab.
{ "name": "My extension", ... "content_scripts": [ { "matches": ["http://*.nytimes.com/*"], "all_frames": true, "js": ["contentScript.js"] } ], ... }
| Name | Type | Description |
|---|---|---|
all_frames |
boolean |
Optional.
Defaults to false ,
meaning that only the top frame is matched.
If specified true ,
it will inject into all frames,
even if the frame is not the topmost frame in the tab.
Each frame is checked independently for URL requirements,
it will not inject into child frames if the URL requirements are not met.
|
Although the execution environments of content scripts and the pages that host them are isolated from each other, they share access to the page's DOM. If the page wishes to communicate with the content script, or with the extension via the content script, it must do so through the shared DOM.
An example can be accomplished using
window.postMessage
:
var port = chrome.runtime.connect(); window.addEventListener("message", function(event) { // We only accept messages from ourselves if (event.source != window) return; if (event.data.type && (event.data.type == "FROM_PAGE")) { console.log("Content script received: " + event.data.text); port.postMessage(event.data.text); } }, false);
document.getElementById("theButton").addEventListener("click", function() { window.postMessage({ type: "FROM_PAGE", text: "Hello from the webpage!" }, "*"); }, false);
The non-extension page, example.html, posts messages to itself. This message is intercepted and inspected by the content script and then posted to the extension process. In this way, the page establishes a line of communication to the extension process. The reverse is possible through similar means.
While isolated worlds provide a layer of protection, using content scripts can create vulnerabilities in an extension and the web page. If the content script receives content from a separate website, such as making an XMLHttpRequest, be careful to filter content cross-site scripting attacks before injecting it. Only communicate over HTTPS in order to avoid "man-in-the-middle" attacks.
Be sure to filter for malicious web pages. For example, the following patterns are dangerous:
var data = document.getElementById("json-data") // WARNING! Might be evaluating an evil script! var parsed = eval("(" + data + ")")
var elmt_id = ... // WARNING! elmt_id might be "); ... evil script ... //"! window.setTimeout("animate(" + elmt_id + ")", 200);
Instead, prefer safer APIs that do not run scripts:
var data = document.getElementById("json-data") // JSON.parse does not evaluate the attacker's scripts. var parsed = JSON.parse(data);
var elmt_id = ... // The closure form of setTimeout does not evaluate scripts. window.setTimeout(function() { animate(elmt_id); }, 200);

Configuration¶
Before you can begin using Flask S3Viewer, you should set up authentication credentials. Credentials for your AWS account can be found in the IAM Console. You can create or use an existing user. Go to manage access keys and generate a new set of keys.
Configure credentials¶
Install AWS CLI.
pip install awscli
If you have the AWS CLI installed, then you can use it to configure your credentials file:
aws configure
Alternatively, you can create the credential file yourself. By default, its location is at ~/.aws/credentials. and Flask S3Viewer is going to use the credential file.
Minimum settings¶
This is a minimal setup for using flask s3viewer. First install the dependency packages.
pip install flask flask_s3_viewer
Import flask and flask_s3_viewer
1 2 3 4 | import flask
from flask_s3_viewer import FlaskS3Viewer
from flask_s3_viewer.aws.ref import Region
|
Initiailize Flask application and FlaskS3Viewer.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | # Init Flask
app = Flask(__name__)
# Init Flask S3Viewer
s3viewer = FlaskS3Viewer(
# Flask App
app,
# Namespace must be unique
namespace='flask-s3-viewer',
# Hostname, e.g. Cloudfront endpoint
object_hostname='http://flask-s3-viewer.com',
# Put your AWS's profile name and Bucket name
config={
'profile_name': 'PROFILE_NAME',
'bucket_name': 'S3_BUCKET_NAME'
}
)
# Register Flask S3Viewer's router
s3viewer.register()
if __name__ == '__main__':
app.run(debug=True, port=3000)
|
The values in the code above are mandatory. If the setting is finished, run your Flask application and visit http://localhost/{namespace}/files
, e.g. http://localhost:3000/flask-s3-viewer/files.
You can get example codes over here.
User Guides¶
It is about various advanced settings.
Multiple bucket settings¶
You can also initiailize multiple bucket.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | ...
s3viewer = FlaskS3Viewer(
...
)
# Init another bucket
s3viewer.add_new_one(
namespace='another_namespace',
object_hostname='http://anotherbucket.com',
config={
'profile_name': 'PROFILE_NAME',
'bucket_name': 'S3_BUCKET_NAME'
}
)
s3viewer.register()
|
Limit the file extensions¶
You can limit the file extensions that are uploaded, if you want.
1 2 3 4 5 6 7 8 9 | s3viewer = FlaskS3Viewer(
...
# allowed extension
allowed_extensions={'jpg', 'jpeg'},
config={
...
}
)
|
Choose the design template¶
Flask S3 Viewer supports the templates below.
| Template namespace | Design type | Description |
|---|---|---|
| base | Default | Not designed at all |
| mdl | Material Design Lite | link |
1 2 3 4 5 6 7 8 9 | s3viewer = FlaskS3Viewer(
...
# Enter template namespace (default: base)
template_namespace='mdl',
config={
...
}
)
s3viewer.register()
|
Controll large files¶
If you want to controll large files (maybe larger than 5MB ~ maximum 5TB), I recommand to set like below. Flask S3Viewer is going to use S3’s presigned URL. It’s nice to controll large files.
1 2 3 4 5 6 7 8 9 | s3viewer = FlaskS3Viewer(
...
# Change upload type to 'presign'
upload_type='presign',
config={
...
}
)
s3viewer.register()
|
but you must do S3’s CORS settings before like set above.
1 2 3 4 5 6 7 8 | <CORSConfiguration>
<CORSRule>
<AllowedOrigin>http://www.yourdomain.com</AllowedOrigin>
<AllowedMethod>GET</AllowedMethod>
<AllowedMethod>POST</AllowedMethod>
<AllowedHeader>*</AllowedHeader>
</CORSRule>
</CORSConfiguration>
|
Use Caching¶
S3 is charged per call. Therefore, Flask S3Viewer supports caching (currently only supports file caching, in-memory database will be supported later).
1 2 3 4 5 6 7 8 9 10 11 12 13 | s3viewer = FlaskS3Viewer(
...
config={
...
# Flask S3Viewer will cache the list of s3 objects, if you set True

The most frightening thing about taking LSD and Ketamine at the same time is the unexpectedness of the effect. I had taken both of these drugs in the past, either alone or in combination with other substances, but I had never taken LSD and Ketamine together until the occasion I describe here. It was an utterly exhausting and slightly frightening experience.
My two friends and I had taken LSD in numerous forms on numerous occasions and it was quickly becoming our drug of choice. Over Christmas I had purchased myself a gram of powder Ketamine and decided to share it with my tripping buddies over a couple of tabs of Acid. At a friend’s birthday party, after an evening of drinking, we took the acid – half tabs all round. It was about 12:30 am and we racked up the Ketamine at about 3am when we were starting to trip - we put Book of Knots on the CD player and divided up the gram.
Having used K in the past, we agreed that we should force ourselves to go for a walk and stagger around. What could be more fun? We went for an ‘adventure’ walk. About fifteen to twenty minutes after taking the K, we all started to feel a little unusual. We were sitting on top of some pallet racking when suddenly we were in a submarine. Unconsciously, we sensed that being on the pallet racking was weird and dangerous. Without speaking, we all climbed down and lay on the ground. At this point, the three of us slipped into something like a K-Hole. Melanie, a friend who had only been drinking and had accompanied us, said that we all fell silent and our faces went slack. We were staring into the sky.
I saw the stars melt and morph into worm holes, one of which I was sucked into. I felt that I was being propelled through time. Heather saw the night sky turn completely white and felt that she was floating in mid-air, one with all matter. Mark felt his consciousness drift into each of our minds – he could see through our eyes and feel our thoughts. We didn’t discuss any of these feelings until the next day – no one could speak. Clearly, this was not a normal trip. No one was laughing. Melanie realised that something was off and picked us up from the ground – myself on one shoulder, Heather on the other. Mark would just have to follow. After a long, staggering, bumbling journey around the block we made it back to the party. Heather and I collapsed on the bed, Mark on the floor.
During the morning I felt a range of experiences - I was incredibly tall, I could crush trees and houses under my feet. My hands and arms were extremely far away. I was constantly being sucked in and out of time. Time travel was exhausting, at times I wanted to cry because I wanted time to be still, to stop ‘rushing’ quickly back and forth through consciousness. I was no longer in a house, I was in a forest, in a video game and the people around me were characters. They talked video-game talk and I couldn’t make it stop, no matter how much I tried.
Speech was nearly impossible. Mark kept gibbering nonsense while trying to work the CD player, not a single intelligible word came out of his mouth for over an hour. Heather lay on her back in the bed mumbling “Why, why? Ketamine bad. Not good. This wasn’t meant to happen…”. We were both feeling nautious. My greatest fear was that I would never come back, that my mind would be irreparably damaged. I simply couldn’t understand how the effects could be so strong, how the trip could so completely control my mind.
The next day, I found sleep impossible.  Mark was the only one who bounced back quite quickly, I can only put this down to the fact that his body size is twice that of myself.
This combination did not do what I expected. It made me trip harder than I’ve ever tripped before and it was uncontrollable and exhausting. Perhaps for the right person this could perfect? I achieved something that I had always wanted to that night – I ticked something off my list of life experiences. I had always wanted to explore the ultimate trip, the complete lack of mental control, the borderline experience. Now I don’t ever need to do that to myself again.

Now that you've experimented with CSRF attacks you should have some idea what is possible. Now it's time to learn the limitations of CSRF attacks and how to prevent them in your applications.
CSRF attacks force a browser to perform actions on the user's behalf. This means there are some limitations on what this kind of attack can do.
CSRF attacks target state-changing requests. This means they can only target endpoints that make some kind of change, such as changing the victim's email address or password, or purchasing something.
The attacker does not recieve the response because it gets sent by the victim's browser. This means CSRF attacks cannot be used to retrieve information. In the example you worked through in this application you learnt how to add and delete entries, but it was not possible to read a user's existing entries.
CSRF attack requests have the same authentication as the victim, because they are sent by that person's web browser. This means endpoints are only vulnerable if they do not require any authentication, or the victom is logged in and has access to perform the action.
CSRF vulnerabilities are much simpler to exploit when they work off GET requests.
It's worth noting that this behaviour is described in the HTTP specification. As well as helping to secure your application, you'll be conforming to best practices about HTTP verb usage.
When performing HTTP POSTs (or DELETE, PUT, PATCH etc) that have a side effect, you should include a secure random token in the request (Synchronizer Token pattern). Most web frameworks provide a way to include CSRF tokens out-the-box, you should use these where possible.
Note: Even if you have some POST/(etc) requests that do not have side-effects it's safer to enable CSRF protection by default for all such requests. This makes it much less likely you'll forget to include the checks on requests that can be exploited.
Note: this approach works best for requests that have a body. If you add tokens to GET or HEAD requests they will appear in the URL. As well as being plainly visible, these are liable to be leaked to proxies, browser caches etc. This is another reason why it's better to restrict side effects to other HTTP methods.
The Origin header was specifically added to the HTTP spec to guard against cross domain attacks. Unfortunately, the header won't always be available so it can't be used as the only of securing your site. By verifying that the Origin matches the site's origin you can be sure the request originated from a genuine user interaction with your application.
The Referer header may also exist on the request. Similarly, verifying that the referer matches the application helps to ensure it is a legitimate request.
In both cases, while it is possible to spoof these headers it isn't possible to do so from a CSRF-style attack unless your site is compromised in another way (e.g. a Cross Site Scripting vulnerability).

Honorable mentions
Scala has too many features to list here and the problem space can be quite different - plus it's a very academic language.
Closure does not improve on Java-esque syntax but rather replaces it with a completelly distinct one.
Ceylon is not as used/matured as the other and quite honestly, I do not know much of it... Other than it has Union Types which is awesome!
